How to Make Sausage Hashbrown Breakfast Casserole
Whipping up this Sausage Hashbrown Breakfast Casserole is surprisingly simple, making it a weekday hero and a weekend showstopper. This dish offers a delightful balance of textures and flavors, featuring a creamy custard that envelops tender chunks of sausage and perfectly browned hashbrowns. The preparation time is about 20 minutes, and it bakes to golden perfection in under an hour, promising a delicious and deeply satisfying meal.
Step-by-Step Instructions
Preheat Oven and Prepare Pan: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter or cooking spray.
Brown the Sausage: In a large skillet over medium heat, cook the breakfast sausage, breaking it up with a spoon as it cooks. Drain off any excess grease and set the cooked sausage aside.
Sauté Vegetables (if using): If you’re adding onion and bell pepper, add them to the same skillet (no need to wash) with a little oil over medium heat. Sauté until softened, about 5-7 minutes. Remove from heat and set aside.
Prepare the Hashbrowns: In a large bowl, combine the thawed hashbrowns. If your hashbrowns are in one large clump, gently break them apart.
Combine Casserole Base: Add the browned sausage, sautéed vegetables (if using), shredded cheddar cheese, and shredded Monterey Jack cheese to the bowl with the hashbrowns. Stir gently to combine all the ingredients.
Whisk the Egg Mixture: In a separate medium bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder until well combined and frothy.
Assemble the Casserole: Pour the egg mixture evenly over the hashbrown and sausage mixture in the large bowl. Stir delicately to ensure everything is coated. Alternatively, you can spread the hashbrown mixture evenly into the prepared baking dish and then pour the egg mixture over the top, gently distributing it.
Bake the Casserole: Pour the entire mixture into the greased 9×13 inch baking dish. Cover the dish loosely with aluminum foil.
First Bake: Bake in the preheated oven for 30 minutes.
Second Bake (Uncovered): Remove the aluminum foil carefully. Continue baking for another 20-25 minutes, or until the casserole is set in the center and the top is golden brown and bubbly. A knife inserted into the center should come out clean.
Rest Before Serving: Let the casserole rest for 5-10 minutes before slicing and serving. This allows it to set up properly.
